Give an example of receptor "binding" - ✔️✔️Morphine binding to Mu receptors to increase
pain relief
What is an *agonist* drug? - ✔️✔️Drug that works with the normal activity of the body
Give an example of an "agonist" drug - ✔️✔️Morphine-pain relief
What is an *antagonist* drug? - ✔️✔️Drug that works against the normal activity of the body

What is a *loading dose*? - ✔️✔️A technique used to fill up receptors quickly by giving a
daily dose every 6 hours. Initial dose fills binding sites
What is a *therapeutic range*? - ✔️✔️Range between effective dose and toxic dose
What is *polypharmacy*? - ✔️✔️When multiple drugs are taken, usually occurs in those that
are 65 and older
Roughly, how many drugs do the elderly take at "home"? - ✔️✔️They take 4 to 6 drugs daily,
having a 50% chance of side effects
Roughly, how many drugs do the elderly take at the "hospital"? - ✔️✔️They take 8 to 10 drugs
daily, having an 100% chance of side effects
Roughly, how many drugs do the elderly take at a "long term care" facility? - ✔️✔️They take

What is the *absorption* phase of drug movement? - ✔️✔️Drug passes from the site of
administration (oral, dermal etc) into body fluids
In what way are drugs administered that they bypass the stomach or liver before distribution?
- ✔️✔️• Thermal
• Buccal
• Sublingual
• Inhaled
What is the *distribution* phase of drug movement? - ✔️✔️Drug is carried from site of
absorption to the site of action
Explain the relationship between free and bound drugs - ✔️✔️Fats and proteins are nonspecific
drug binding sites, meaning these sites are not cell receptors. When drugs bind to these sites,
it stops the drug from binding to the cell receptor. When the drug is released from the fat or
plasma protein it becomes available to bind to cell receptors and produce an effect
When does a drug become "active"? - ✔️✔️A drug becomes active when it is displaced from a
fat or protein. If two drugs were competing for the same protein binding sites, the stronger
protein-affinity drug will displace the weaker protein-affinity drug, displacing the weaker
drug making it active.
